78. Yet another resignation today...

A member of New Jersey Gov. Chris Christie's administration who has been subpoenaed in the investigation of the September bridge lane closures has resigned.

Christina Genovese Renna — one of 17 people with ties to Christie subpoenaed by a legislative panel — exited the governor's office Friday, according to a statement provided to NBC News on Sunday by her lawyer, Henry Klingeman.

In the statement, Renna said her resignation "reflects a decision I have been considering since shortly after the election." Christie won a second term in office in November.

Renna reported to Bridget Anne Kelly, Christie's since-fired deputy chief of staff, who apparently set the traffic jam on the George Washington Bridge in motion with an email to David Wildstien, a Christie appointee and ally at the Port Authority.
